One concern I have with the ad placement is that it randomly chooses a paragraph to put the add under. So there will be instances where someone posts, "Hey visit this great site:" and your ad will be randomly inserted under that in the place where the person had put the link. If Adsense people see that they will see it as a violation. I would be more comfortable with the ad always at the end of the post in the signature. Or in the begining of the post. That way what they write cannot be mistaken to encourage clicking on the link.
